Rules of the messageboard:

Thou shalt not swear.
Thou shalt not insult other people or korfball clubs (on the public messageboard at least).
Thou shalt not generally be naughty. Thou shalt not try to push thy luck.

Failure to comply with the above rules will result in a warning, a second offence will result in a formal warning and a third offence will result in expulsion from the system. Of course if you try hard enough you may skip the first two.
